Return to Jupiter

A foreign atmospheric substance contaminates the Ikarus.

A computer malfunction sends the spaceship of course and in a collision course with Earth.

Michael and Gerard go out onto the surface of Mars to get help from a nearby hydrogenation plant.

Michael and Gerard return to the ship with Glovic and Selby. Glovic and Selby want to help with the repair by using their High Tech computer, but they require unlimited access to all programs of the ship making Kumiko very suspicions of their true intentions.

While repairs on the Ikarus continue, Michael and Gerard go out to search for Zac, Abrahamk, the track vehicle and the robot, Quadro.

Kumiko and Gerard start work at the hydrogenation plant in order to investigate Selby and Golvic.

The Ikarus leaves Mars and sets course for Ganymed. The navigation system failed again however and the crew discovers that there is a virus in the ship's system.

An Asteroid named Pallas is on the same course as the Ikarus. A way out of this would be to attach the ship to the Asteroid.

The ship has arrived at Ganymed and as the crew prepares for landing they realize that the colony has been destroyed.

Selby says he will tell the crew where the fuel reserves are if they leave him at the station.

Dent leaves the children on board the Ikarus and Gerard takes Command. In the middle of the night Selby and Golvic turn up threatening to sabotage Dent's ship if the children do not surrender.

The Ikarus, while towing Selby's spaceship, is accelerating on collision course with Terminex, Gerard must destroy the ship, before it strikes Terminex to prevent a disaster.
